Definitions

  • the invention relates to a method and a system for coating a scaled hot strip.
  • molten zinc For galvanizing the surfaces of a hot strip, e.g. in hot-dip galvanizing, it is known to first heat the hot strip in a continuous furnace to a temperature of around 500 ° C, in order to then pass the hot strip through a bath of molten zinc (at around 450 ° C). As soon as the hot strip leaves the bath melt, the coating thickness for the zinc is adjusted by means of air wiping nozzles.
  • the galvanizing of hot strip according to the hot-dip coating principle or hot-dip galvanizing has the disadvantage that the strip surface of the hot strip is heated to well over 400 ° C. As a result of this heat treatment, the hot strip loses some of the material properties previously set in the hot rolling mill.
  • EP 0 863 222 A1 it is known to permanently couple the pickling and galvanizing process with a cold rolling process in a complete plant in a continuous line.
  • the hot strip is also always subjected to cold rolling in order to bring the hot strip to the desired finished thickness.
  • Carrying out cold rolling has the disadvantage connected that the hot strip solidifies and / or loses its preset material properties. The material properties of the hot strip must then be restored in a subsequent annealing process.
  • a method and a corresponding system for coating a metal strip are known.
  • a metal strip wound into a bundle is first unwound, and then the beginning of the metal strip is threaded into a continuous coating chamber, passed through the continuous coating chamber and the metal strip is then wound into a bundle after coating.
  • the end of the metal strip is threaded out of the continuous coating chamber, with further metal strips, each also wound into a bundle, subsequently being passed individually through the continuous coating chamber in the same way.
  • a method for producing a baffle plate in which a thermoplastic polymer foam layer is applied to a surface of a first metal sheet, a second metal tape then being applied to this polymer foam layer, and then the first metal tape, the thermoplastic polymer foam layer and the second metal tape by exposure to temperature Applying pressure are connected to one another to form a composite component.
  • the invention is based on the object of metallically coating scaled hot strip in one process step, whereby preset material properties of the hot strip should not be lost.
  • the invention provides a system for coating a scaled hot strip, which comprises a continuous treatment line in which the hot strip is moved in one direction of movement, with a pickling device for preparing the surfaces of the hot strip and at least one first coating device being provided in the treatment line .
  • a coating can be applied to at least one prepared surface of the hot strip, for example in the form of a zinc layer.
  • the first coating device is designed in such a way that, if it is put into operation, the hot strip is coated on at least one side thereof at a temperature of 100 ° C.
  • a second coating device which - viewed in the direction of movement of the hot strip - is arranged downstream of the first coating device, an additional coating consisting of a plastic film lamination being applied to at least one surface of the hot strip by means of the second coating device.
  • the invention is based on the essential knowledge that a hot strip retains or does not lose its material properties previously set in a hot rolling mill in the course of its coating, because all processes according to the present invention run at low temperatures of 100 100 ° C. In other words, the preset material properties of a hot strip are largely retained during pickling and subsequent coating, e.g. galvanizing.
  • a hot strip is brought to the treatment line of the plant according to the invention directly after the hot rolling mill, where its surfaces are prepared in a continuous process, e.g. descaled, and then coated with metal.
  • the hot strip is coated immediately after its surface (s) have been prepared for coating, e.g. by means of an upstream pickling process.
  • the hot strip is not subjected to any processes, e.g. in the form of cold rolling or the like, in which the preset material properties of the hot strip would be changed or impaired.
  • step (i) of the method the surfaces of the hot strip are prepared by means of a pickling device. This has the advantage that it not only removes the layers of scale produced during hot rolling, but also an oxide layer formed on the hot strip effectively from the surfaces of the hot strip.
  • the hot strip can be coated by means of the first coating device according to the principle of electrolysis. This applies in particular to step (iii) of the process according to the invention.
  • the hot strip is expediently coated on one or both surfaces thereof, ie on its upper side and / or lower side.
  • the hot strip is trimmed at its side edges before its surfaces are prepared for the subsequent coating. This ensures a clean coil with defined and coated side edges.
  • trimming of the hot strip can be carried out by scissors which - viewed in the direction of movement of the hot strip within the treatment line - are arranged upstream of the pickling device.
  • a film lamination unit is arranged downstream of the first coating device, by means of which the hot strip is laminated with a plastic film.
  • the hot strip is provided with a roller coating on at least one surface, for example by contact with corresponding rollers that are exposed to a medium that is applied to at least one surface of the Hot strip is to be applied, are soaked.
  • the hot strip can thereby be provided with an acrylic coating and / or with a chromatic coating or the like.
  • a predetermined roughness is set for the hot strip on its surfaces.
  • a skin pass stand is arranged downstream of the first coating device, through which the hot strip is passed.

  • an oiling machine in particular downstream of the second coating device, by means of which an oiling machine can be applied to an upper side and / or an underside of the hot strip
  • the system according to the invention can be provided for the system according to the invention that - if necessary - the first coating device is not put into operation when the hot strip is moved or transported through the treatment line. In this way it is possible, for example, to carry out only the pickling process for the hot strip, but without subsequently galvanizing the hot strip.
  • the possible product range for the hot strip can be increased. For example, it is thus possible to pickle normal steel strips with pickling acid to produce a pickled and oiled strip surface by switching off the first coating device for applying a zinc coating.
  • the system according to the invention can also be used when the first coating device remains out of operation.
